Developing minimum clinical standards for physiotherapy in South African ICUs: A qualitative study.

RATIONALE, AIMS, AND OBJECTIVES: Physiotherapists are integral members of the intensive care unit (ICU) team. Clinicians working in ICU are dependent on their own experience when making decisions regarding individual patient management thus resulting in variation in clinical practice. No formalized clinical practice guidelines or standards exist for the educational profile or scope of practice requirements for ICU physiotherapy. This study explored perceptions of physiotherapists on minimum clinical standards that ICU physiotherapists should adhere to for delivering safe, effective physiotherapy services to critically ill patients. METHOD: Experienced physiotherapists offering a service to South African ICUs were purposively sampled. Three focus group sessions were held in different parts of the country to ensure national participation. Each was audio recorded. The stimulus question posed was "What is the minimum standard of clinical practice needed by physiotherapists to ensure safe and independent practice in South African ICUs?" Three categories were explored, namely, knowledge, skill, and attributes. Themes and subthemes were developed using the codes identified. An inductive approach to data analysis was used to perform conventional content analysis. RESULTS: Twenty-five physiotherapists participated in 1 of 3 focus group sessions. Mean years of ICU experience was 10.8 years (±7.0; range, 3-33). Three themes emerged from the data namely, integrated medical knowledge, multidisciplinary teamwork, and physiotherapy practice. Integrated medical knowledge related to anatomy and physiology, conditions that patients present with in ICU, the ICU environment, pathology and pathophysiology, and pharmacology. Multidisciplinary teamwork encompassed elements related to communication, continuous professional development, cultural sensitivity, documentation, ethics, professionalism, safety in ICU, and technology. Components related to physiotherapy practice included clinical reasoning, handling skills, interventions, and patient care. CONCLUSIONS: The information obtained will be used to inform the development of a list of standards to be presented to the wider national physiotherapy and ICU communities for further consensus-building activities.

Developing minimum clinical standards for physiotherapy in South African intensive care units: the nominal group technique in action.

RATIONALE, AIMS AND OBJECTIVES: Physiotherapists form an important part of the inter-professional team that cares for critically ill patients in intensive care units (ICU). No formalized clinical practice guidelines or standards exist for the educational profile or scope of practice requirements for physiotherapy within critical care, which poses a threat to physiotherapy practice and professional credibility. METHODS: The aim of this paper was to describe the nominal group technique (NGT) used to identify the minimum standards of clinical practice needed by physiotherapists to ensure safe and independent practice in South African ICUs. RESULTS: Twenty-five subjects participated in one of three forums. Sixty-six concepts were considered in the three domains (knowledge, skills and attitudes). Not all concepts were discussed by all three focus groups. Just over half (54% n=14) the concepts generated in the knowledge domain; a third of the concepts (35% n=7) generated in the skills domain and only 10% (n=2) of attitudes were consistently raised by all three groups. Almost two-thirds of the concepts generated (62% n=41) were considered in more than one domain. Only six concepts reached the threshold consensus level across all three focus groups, four knowledge parameters and two skills. CONCLUSION: The NGT allowed for the cross-stimulation of ideas in an engaging yet anonymous and structured manner. The importance of discussion in reaching consensus is highlighted. Going forward, it is intended to use the concepts generated through this process as the foundation for further consensus-building activities among the wider physiotherapy and intensive care communities.

The use of a weaning and extubation protocol to facilitate effective weaning and extubation from mechanical ventilation in patients suffering from traumatic injuries: a non-randomized experimental trial comparing a prospective to retrospective cohort.

PURPOSE: Many patients who have suffered traumatic injuries require mechanical ventilation (MV). Weaning is the transition from ventilatory support to spontaneous breathing. The purpose of this study was to determine whether the use of a nurse and a physiotherapist-driven protocol to wean and extubate patients from MV resulted in decreased MV days and intensive care unit (ICU) length of stay (LOS). METHODS: A prospective cohort of 28 patients (Phase I), weaned according to the protocol developed for the Union Hospital Trauma Unit, was matched retrospectively with a historical cohort of 28 patients (Phase II), weaned according to physician preference. Pairs in the two groups were matched for gender, age, type, and severity of injury. RESULTS: For mean MV days, the groups did not differ statistically significantly (p 0.3; 14.4 days vs. 16.3 days), although the reduction in MV is clinically significant in view of the complications of additional MV days. The difference of 0.2 days for ICU LOS was not statistically significant (p = 0.9; 20.8 days vs. 21.0 days) demonstrating that the reduction in MV days may not result in the reduction of ICU LOS. The rate of re-intubation was similar between the groups (Phase I = 3/28 vs. Phase II = 4/24). CONCLUSION: The use of a weaning and extubation protocol led by nursing staff and physiotherapists resulted in a clinically significant reduction in MV time, reducing risk of ventilator-associated complications. The role of physiotherapists and nursing staff in weaning and extubation from MV could be greatly expanded in South African ICUs.
